Statement of Task

assess the benefits, risks, and sustainable scale potential for carbon dioxide removal and sequestration approaches in terrestrial and coastal environments; and

increase the commercial viability of carbon dioxide removal and sequestration;

Define the essential components of a research and development program and specific tasks required to answer these questions;

Estimate the costs and potential impacts of such a research and development program to the extent possible in the timeframe of the study.

Recommend ways to implement such a research and development program.

�
The list of CDR approaches to be examined would include land and coastal (i.e., tidal wetlands, seagrass meadows, and mangroves) ecosystems management, accelerated weathering, bioenergy with capture, direct air capture, geologic sequestration, and other approaches deemed by the study committee to be of similar viability in terrestrial and coastal environments.

NOTE: The statement of task was slight edited in September 2017 to clarify that the scope of this study is limited to the assessment of any viable approach in the terrestrial and coastal environments.
